Dane są wielomiany W(x)=-6x+3,P(x)=x^2+2x-1 oraz Q(x)=5x^3-x+4.Wielomian 1/3W(x)(P(x)-Q(x)) można zapisać w postaci:
a.10x^4-7x^3+5x^2-13x-5
b.10x^4-7x^3-5x^2+13x-5
c.10x^4-7x^3+5x^2+13x+5
d.10x^4+7x^3-5x^2+13x-5
Proszę,pomóżcie!!!

1/3w(x)(P(X)+Q(X)=1/3*(-3x+6)(x2-2x+1+5x3+x-4)=(-x+2)(5x3+x2-x-3)=
-5x3-x3+x2+3x+10x3+2x2-2x-6=4x3+3x2+x-6
*-mnozenie
5x2-5 do kwadratu niewiem czy dobrze ale chyba tak
1/3w(x)(P(X)+Q(X)=1/3*(-3x+6)(x2-2x+1+5x3+x-4)=(-x+2)(5x3+x2-x-3)=
-5x3-x3+x2+3x+10x3+2x2-2x-6=4x3+3x2+x-6
